Walking tour of the Roche Bleue Chappe telegraph station

There were three of them in Maurienne, and each post had its own name.
On this surprising walk, you'll come near the monolith, that iconic limestone
giant. Picture this: cabins positioned every 10 kilometres between Paris
and Venice. At the heart of this enchanting forest dotted with Scots pines,
imagine the exchanges of visual signals between Mollard Fleury in Sardières,
Courberon in Avrieux and Plan de l’Ours in Saint-André.
To get a better grasp of how this ingenious system worked, visit the other
two sites. Easily accessible, they're suitable for all ages. Want to find out

guided tours throughout the summer. A brochure is available at tourist offices.
